Objective: to examine the care provided to women affected by breast cancer and who has performed axillary lymphadenectomy. Method: integrative review conducted in the databases LILACS and PubMed between 2000 and 2012, leaving the question << What care is provided to prevent lymphedema in women who underwent lymphadenectomy? >> Resulting in 18 articles, analyzed under the following variables: author, title, methodology, year, journal, goal, prevention and control of lymphedema therapies and adherence to rehabilitation. Results: three categories are identified for rehabilitation of patient: prevention and control, therapies and adherence. Conclusion: preoperative is poorly addressed by; emphasizes the importance of home visits as part of rehabilitation, which is effective with the accession of the patient who needs information for its follow-up, no need for a guideline for this type treatment.

The immunohistochemistry regarding the expression of cyclooxygenase-2 (COX-2) for the woman’s breast cancer became a routine application due to the biological relevance. It is possible that COX-2 is closely related to tumor angiogenesis, inhibition of apoptosis mechanism, adhesion and metastasis. Herewith the COX-2 expression contributes to verify the malignant potential of the breast cancer. However it is slightly used in female dog’s spontaneous breast carcinomas. Keeping this in mind, the \cox-2 inhibitions appear as a promising perspective for the prevention and treatment of some sorts of cancer. The present dissertation had as main purpose to show the occurrence of the COX-2 expression in some of the female dog’s spontaneous breast carcinomas

O evento de splicing alternativo tem como resultado a geração de diversos produtos a partir do precursor do RNA mensageiro de um único gene, sendo o responsável, assim, pelo aumento da variedade de transcritos e proteínas existentes em uma célula. Estima-se que cerca de 90% dos genes humanos estejam sujeitos a este tipo de processamento. O funcionamento adequado do processo de splicing depende do reconhecimento correto dos limites entre trechos intrônicos e exônicos pela maquinaria enzimática, que se dá através do reconhecimento de diversos sinais, como os sítios de splicing 3’ e 5’, o trato de polipirimidina, a seqüência “branch”, e pequenas seqüências presentes em exons e introns, próximas aos sítios de splicing, que promovem ou inibem a inclusão de trechos na fita de RNA madura. É fato comprovado por diversos estudos que mutações nas seqüências sinalizadoras de splicing podem modificar o padrão de processamento de um gene. Acreditase que variações genéticas individuais possam modificar a suceptibilidade a diversas doenças, entre elas o câncer, que trata-se, atualmente, da doença que mais gera óbitos no mundo (13% do total). Recentemente, Sjoblom et al. (2006) e Wood et al. (2007) mapearam mutações não silenciosas encontradas em 1718 genes em linhagens de câncer de mama e colorretal. Neste trabalho, investigamos os efeitos dessas mutações somáticas presentes em câncer no padrão de splicing celular. Para tanto, nos focamos nas 201 mutações encontradas em quatro linhagens de câncer de mama (HCC1954, HCC1599, HCC1143 e HCC2157). A partir dos dados obtidos pela técnica de “Exon Array” (Affymetrix) e do mapeamento das mutações, foi realizada uma seleção dos genes aonde haviam mutações e eventos de splicing alternativos específicos a somente uma das linhagens celular, e cuja distância...

The paper presents the radiometric parameters determined by the medical physicist during routine radiotherapy planning service in cases of breast cancer . The contours of the breast volume in patients undergoing radiation breast tumors at the Hospital das Clinicas, Faculty of Medicine , UNESP, Botucatu ( HCFMB ) during the year 2012 were analyzed . In order to analyze the influence of physical and radiometric parameters for the determination of the dose distribution of irradiated breast volume , four measurements of isodose curves were prepared in four different heights breast , and compared with the isodose curves plotted computationally . In the routine of planning , the medical physicist must determine the isodose curve that gives the best dose distribution homogeneity in the irradiated volume . The choice of the treatment plan can be done by dedicated computer systems , which require significantly costly investments available services having better financial support . In the Service of Medical Physics , Department of Radiotherapy , HC FMB , we use a two-dimensional software for determination of isodose curves , however , this software is out of date and frequently becomes inoperable due to the lack of maintenance and it is a closed system without feasibility of interference from computer professionals . This fact requires manual preparation of isodose curves , which are subject to uncertainties due to the subjectivity in the clinical interpretation of medical radiation oncologist and medical physicist responsible for planning , plus dispendiar significant calculation time . The choice of the optimal isodose curve depends on the energy of the radiation beam , the geometry and dimensions of the irradiated area . The contours of the breast studied in this work evaluations showed that , for a given energy input , such as the energy of 1.25 MeV of gamma radiation Unit Telecobaltoterapia , the determination of the percentage depth dose ( PDP ) ...
